Abstract
With the development of micro electronic technology and embedded system in China, the traditional automobile anti-theft alarm system in the industry can not meet the needs of customers. In order to improve the traditional car anti-theft alarm system in the control of the short board problem, in this graduation project, will use relatively advanced, fast, intelligent control mechanism.The control brain of the system is the core controller of the 51 series embedded development system, which mainly uses digital control technology to convert the input continuous analog voltage signal into discrete digital signal and give alarm hints. The car anti-theft alarm system design has intelligent control, can only alarm and other functions, and cost-effective, accurate, low energy consumption, simple production and other characteristics, has brought a great impact on people's lives, is very popular in the market.
The intelligent control system design mainly from the domestic and foreign development, the choice of hardware control components, according to the control principle to draw the hardware circuit, control system software program design and development, software and hardware joint adjustment simulation four aspects in detail. The control system uses AT89C51 embedded development system, sensor signal acquisition circuit, alarm circuit, data conversion circuit, reset circuit and clock circuit and so on to constitute the automobile anti-theft alarm system. C language was used for code development, Keil software was used for code design and writing, Proteus was used for simulation, and finally the system performance requirements were met.
Keywords: AT89C51. Car theft; Call the police; Single chip microcomputer
